Minutes later, the officers reported another splash and found that the same dog had jumped back into the water and swam out to the middle of the lagoon. They couldn't reach the dog, and a park's department employee's net was too short, so a fire department boat was called in.

While waiting for the boat, the dog appeared to struggle and eventually wound up wrapped in weeds and a tangled fishing line with a hook and bobber.

Spingola jumped into the water to retrieve the dog.

The dog was taken to Milwaukee Area Domestic Animal Control Commission for an exam. MADACC officials said they're hoping the dog's owners will come forward.
